Satisfactory Dedicated Server Setup Guide

Server requirements

A Satisfactory dedicated server needs strong single-thread CPU performance and plenty of RAM. Minimum: 4 GB RAM for a new world. Recommended: 6 to 8 GB for mid-game factories, 10 to 12 GB for late-game megabases. NVMe storage reduces save/load times as save files can grow past 500 MB.

Installation via SteamCMD

The server uses SteamCMD app ID 1690800 and supports anonymous login:

steamcmd +force_install_dir /opt/satisfactory \
  +login anonymous \
  +app_update 1690800 validate \
  +quit

Start with ./FactoryServer.sh -unattended. On first launch, connect via the in-game Server Manager, claim the server, and set an admin password.

Ports to open

Three UDP ports are required: 7777 (game traffic), 15777 (server query), and 15000 (beacon). All must be open in your firewall for players to connect and for the server to appear in the server browser.

Key configuration

Edit FactoryGame/Saved/Config/LinuxServer/GameUserSettings.ini:

• MaxPlayers: default 4, increase to 8 or 16 (monitor performance).
• mAutoPause: true pauses when no players are online. Set to false for continuous production.
• mAutoSaveOnDisconnect: saves when the last player leaves. Keep enabled.

Save management

Saves are in FactoryGame/Saved/SaveGames/server/. The server autosaves every 5 minutes by default. Set up a daily backup with tar/cron and prune backups older than 14 days. You can transfer a single-player save to the server by copying it into this directory.

Performance tips

Factory complexity is the main bottleneck. Reduce conveyor belt segments by using manifolds, build vertically to limit entity counts per area, minimize vehicles with autopilot (prefer trains), and restart the server every 24 to 48 hours to clear accumulated memory.

Can I use mods on a dedicated server?

Yes. Install mods via Satisfactory Mod Manager (SMM) in the server directory. All players must have matching mod versions.
